1. Strengthen the feeding of lamb during lactation Ewe's colostrum is rich in protein, fat and other nutrients and antibodies. It has anti-disease and laxative effects. After lambs are born, they eat colostrum in time to enhance their physical fitness, disease resistance, and excretion. Dung has a very important role. Newborn lambs should be supplemented early, that is, 10 days to the grass, 20 days of feeding, lambs after 1 month of age given appropriate exercise, the spring lamb can be 10 days of age to exercise. For special circumstances, artificial feeding methods, such as bottle feeding method and pot feeding method, may be used, but it is necessary to pay attention to timing, constant temperature, qualitative, quantitative, and wipe the mouth after feeding to prevent mutual biting and cause diseases. Through the above measures, the lamb grows rapidly throughout the lactation period, and the daily gain can reach about 300 grams. 2 Raise lambs. Raising lambs are dripping milk at 3-4 months of age. The age of the first mating is called bred sheep. At this point, the male and female breeding groups should be formed separately. When the broiler is in good condition in the first few months, although the weight gain is not as rapid as the lactation period, it can still increase the daily weight by more than 150 grams before the age of 8 months. It needs to dry the feed between 0.7-1 kg per day. Need to supplement crude protein content of 15% -16%, about 300 grams of mixed concentrate. Mixed concentrate formula: 50% corn, 25% peas or oil residue. Bran 25%-30%, bone meal 2%, salt 0.5%. Goats have the fastest weight gain from 1 to 5 months of age. With the extension of the feeding period, the feed material consumption per unit weight gains exponentially, and the conversion rate of forage material is reduced. Therefore, the method of using lambs for fattening and slaughtering is to increase the feed conversion rate. And effective ways of economic efficiency. 3 feed additives 3.1 sheep fattening compound feed additives are composed of trace elements (Fe Cu Mn Zn Se), rumen metabolism, growth promoters, etc., suitable for the current year lamb and the elimination of ram, old and weak adult sheep fattening. The grazing sheep supplemented the concentrate and the mixture was fattened for 90 days. The average daily weight gain was 134 grams, and 4.4 kg of the mixture was consumed per kilogram of weight gain. Improve the fattening effect and economic benefits, shorten the fattening period, reduce labor consumption, and save feed. 3.2 monensin sodium, also known as rumen. Monensin, Mengningsu. The role is to control and increase the efficiency of ruminal fermentation, thereby increasing the rate of weight gain and feed conversion, with 25-30 mg per kg of ration. 3.3 Ethanol, also known as fast-breathing spirit, spray acid and so on, for synthetic antibacterial agents. Can affect the body's metabolism and promote protein assimilation. The amount of 50-80 mg/kg of ration is mixed in the feed. 3.4 Bacitracin Zinc is a bacteriostasis and growth promoter. It is beneficial to the absorption of nutrients in the intestine and improve feed utilization. The amount of lambs used is 10-20 mg per kilogram of mix. 3.5 phosphate pulse commodity name cattle sheep music. It is a new non-protein nitrogen feed additive for ruminants. Its hydrolysis rate in the stomach is significantly lower than that of urea, which can promote the physiological metabolism of the bred sheep and the absorption of nitrogen, phosphorus and calcium. The dosage is 10 grams per day. 3.6 Urea is suitable for use in adult sheep, and is usually fed at a content of 1.5%-2% in the concentrate. Pay attention to the following items: 1 Feeding amount: The number of sheep fed each day is 0.02% of the body weight of the sheep, that is, 10-15 grams of adult ewe feeding, 6-8 grams of sheep aged 6 months or older, and the first feeding amount can only be specified. The 1/10 feed is gradually increased, and can be added to the prescribed amount after 10 days. 2 To prevent nitrogen poisoning, urea cannot be fed alone, nor can it be dissolved in water, and can not drink water within half an hour after feeding; 3 Once fed , generally do not interrupt, in order to ensure that the body and rumen microorganisms digestion and absorption adaptability of urea, such as intermittent feeding, should be gradually increased gradually; 4 pairs of diseased sheep, weak sheep less fed or not fed; 5 poisoning rescue: 20% -30% sugar water, but also 0.5% vinegar 0.2-0.5 liters or 1-3 liters yogurt filling.
